Mushrooms: High Fodmap Foods To Avoid

why are mushrooms high fodmap

Mushrooms are a versatile ingredient, with a variety of textures and flavours, and they are a great source of vitamin D. However, they are also high in FODMAPs, which stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols. FODMAPs are a group of carbohydrates that can be difficult for some people to digest, and can cause symptoms such as bloating, gas and stomach pain. While not all mushrooms are high in FODMAPs, many common varieties are, and it is important to understand the FODMAP content of different mushrooms to avoid digestive problems.

Characteristics Values

Fresh shiitake and portobello mushrooms are high in polyol mannitol

Shiitake mushrooms have a chewy and meaty texture with a rich, strong, earthy flavour. They can be roasted, pickled, or eaten raw as a side dish for chicken, beef, or seafood. Dried shiitake mushrooms have a smoky, rich flavour and increased nutritional value, but they are still high in FODMAPs. However, a half serving of dried shiitake mushrooms is considered low FODMAP.

Portobello mushrooms also contain high amounts of mannitol and are known for their rich, savoury, earthy, and meaty flavours, as well as their firm, dense textures. They are commonly used in stuffed mushroom recipes and are ideal for roasting, sautéing, searing, and grilling. While portobello mushrooms are high in FODMAPs, a quarter of a mushroom is considered a low FODMAP serving size for children.

It is important to note that not everyone with IBS reacts to all types of FODMAP foods, and tolerance levels can vary. Working with a specialised dietitian can help individuals navigate which mushrooms suit their sensitive tummies. Additionally, portion size matters, and some mushrooms that are high in FODMAPs in larger servings may be suitable in moderate or low quantities. For example, dried porcini mushrooms are high in FODMAPs, but a moderate serving of 2 tablespoons is generally considered acceptable. Similarly, canned button mushrooms are low FODMAP because the FODMAPs leach into the brine, reducing the overall FODMAP content of the mushrooms.

Canned button mushrooms are low FODMAP due to the water-soluble FODMAPs leaching out

Canned button mushrooms are suitable for a low-FODMAP diet. FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols. Mushrooms are a good source of vitamin D, which is essential for optimal muscle and bone health, and they are also a great meat substitute for plant-based diets.

However, fresh button mushrooms are high in FODMAPs, specifically mannitol and fructans. Mannitol is a polyol (a sugar alcohol) that can contribute to IBS symptoms due to its role as a fermentable carbohydrate. It is also present in other foods, including watermelon, cauliflower, celery, butternut squash, sweet potato, and mange tout. Fructans are also a type of FODMAP that can be found in mushrooms.

When button mushrooms are canned, the water-soluble FODMAPs leach out into the water, lowering the overall FODMAP content of the mushrooms themselves. This makes drained canned button mushrooms low in FODMAPs, with a generous serving size of up to 250 grams. Canned button mushrooms have a milder and slightly saltier flavour than fresh mushrooms due to the brine they are packed in, and their texture is softer and more uniform.

It is important to note that while canned button mushrooms are low in FODMAPs, other types of mushrooms may be high in FODMAPs. For example, shiitake, portobello, and saffron milkcap mushrooms are high in FODMAPs due to their high polyol mannitol content. Dried porcini mushrooms are also high in FODMAPs, specifically mannitol, in large amounts. Therefore, it is recommended to consume them in moderate serving sizes of around 15 grams or two tablespoons.

Saffron milkcap mushrooms are high FODMAP due to their mannitol content

Saffron milk cap mushrooms, also known as Lactarius deliciosus, are a colorful mycorrhizal variety of mushrooms belonging to the Russulaceae family. They are native to Europe and are considered a foraged delicacy, especially in Russia and Spain. These mushrooms have a distinctive bright orange-gold cap with a granular surface and a white to carrot-colored latex-like liquid when cut. They have a crunchy texture and a nutty, earthy, and woody flavor, making them suitable for various cooked dishes.

While saffron milk cap mushrooms offer nutritional benefits, they are also high in FODMAPs, specifically mannitol, a type of polyol. Mannitol is a sugar alcohol that can contribute to irritable bowel syndrome (IBS) symptoms as it is a fermentable carbohydrate. FODMAPs, which stand for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols, are carbohydrates that can trigger digestive problems in individuals with IBS.

The high mannitol content in saffron milk cap mushrooms is not unique, as many common varieties of mushrooms are also high in mannitol and are generally avoided during the low FODMAP phase of a low FODMAP diet. However, it is important to note that tolerance to mannitol can vary, and some individuals with IBS may still be able to include certain mushrooms in their diet without experiencing symptoms.

To manage IBS symptoms while enjoying mushrooms, portion size is crucial. For example, while dried porcini mushrooms have high mannitol levels, a moderate serving of 15 grams or 2 tablespoons is considered acceptable. Additionally, canned button mushrooms are suitable for a low FODMAP diet because the water-soluble FODMAPs leach out into the brine during canning, reducing the overall FODMAP content.

Enoki mushrooms are high FODMAP and contain the polyol mannitol

FODMAP is an acronym for Fermentable Oligo-, Di-, Mono-saccharides and Polyols—short-chain carbohydrates that the small intestine struggles to absorb. FODMAPs are known to cause symptoms in people with IBS.

Enoki mushrooms are high in FODMAPs and contain the polyol mannitol. They are used in Asian recipes and have a chewy texture and nutty, sweet, and earthy flavor. Enoki mushrooms should be avoided on a low-FODMAP diet. However, if your child is not sensitive to polyols, they can be used in stir-fry or risotto.

While Enoki mushrooms are high-FODMAP, not all mushrooms need to be avoided on a low-FODMAP diet. For example, fresh oyster mushrooms are low-FODMAP and canned champignon (button) mushrooms are low-FODMAP in 1/2 cup servings. This is because the FODMAP content leaches into the brine, reducing the overall FODMAP content. Fresh Shimeji mushrooms are also suitable for a low-FODMAP diet in amounts of up to 750g.

It is important to note that individual tolerance to FODMAPs varies, and a specialized dietitian can help determine which mushrooms are suitable for your dietary needs.

Dried black chanterelle mushrooms are high FODMAP due to polyol sorbitol

Mushrooms are a type of fungus that is commonly known as a vegetable. They are used in cooking and are popular in European, Asian, and South American cuisines. They are a source of fibre and protein and contain vitamins and minerals, including B vitamins, phosphorus, selenium, potassium, copper, and vitamin D. Mushrooms are also a source of prebiotic fibre, which supports gut bacteria diversity. Vitamin D is essential for maintaining healthy bones, teeth, and muscles, and mushrooms grown under ultraviolet (UV) light can contain up to 10 µg of vitamin D per 100 g of mushrooms.

While mushrooms offer various health benefits, they can be high in FODMAPs, which stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. FODMAPs are carbohydrates that can cause digestive problems in people with IBS. Many common varieties of mushrooms are high in mannitol, a type of polyol, and should be avoided during the low FODMAP phase of a low FODMAP diet. Other mushrooms, such as oyster mushrooms, are considered low FODMAP and can be enjoyed in larger quantities.

Dried black chanterelle mushrooms, also known as black trumpets, are unique among mushrooms in that they are high in the polyol sorbitol rather than mannitol. Sorbitol is less common in mushrooms and is only present in chanterelle mushrooms. Dried black chanterelles are prized in gourmet cooking for their intense flavor and versatility. They have a rich, earthy flavor with subtle smoky and fruity undertones, and their taste becomes more intense when dried, adding depth to dishes.

If you are sensitive to mannitol but can tolerate sorbitol, dried black chanterelle mushrooms may be a suitable option for you. However, if you are following a low FODMAP diet, it is important to check the Monash app to ensure you are consuming safe quantities, as portion size is crucial. For children sensitive to FODMAPs, it is advisable to use mushrooms with polyols sparingly or avoid them altogether.
